One other thought, please reconsider the key lookup for ${identifier}.
I think retaining the braces in the key is a mistake. The purpose of
the braces was to allow trailing characters without intervening
whitespace. Extending it to have special meaning for SafeDicts was
probably not the way to go.
As a result, the example in the PEP doesn't work anymore:
>>> mapping = dict(name='Guido', country='the Netherlands')
>>> s = dstring('${name} was born in ${country}')
>>> print s % mapping
Traceback (most recent call last):
File "C:\nondist\sandbox\string\pep292.py", line 124, in -toplevel-
print s % mapping
File "C:\nondist\sandbox\string\pep292.py", line 108, in __mod__
return self._modstr % other
KeyError: '{name}'

P.S. The PEP example is also missing the rightmost single quotation
mark.
